Provide implementations of advanced data structures
npx skills add a5c-ai/babysitter --skill advanced-ds-library --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Advanced Data Structures Library Skill ## Purpose Provide implementations and guidance for advanced data structures commonly needed in competitive programming and complex algorithmic problems. ## Capabilities - Treaps, Splay trees, Link-cut trees - Persistent data structures - Wavelet trees - Heavy-light decomposition - Centroid decomposition - Rope data structure - Order statistics tree ## Target Processes - data-structure-implementation - advanced-graph-algorithms - cp-library-creation ## Data Structure Catalog ### Balanced BSTs - Treap (randomized BST) - Splay Tree (self-adjusting) - AVL Tree - Red-Black Tree ### Tree Decomposition - Heavy-Light Decomposition - Centroid Decomposition - Euler Tour Technique ### Advanced Structures - Link-Cut Trees (dynamic trees) - Wavelet Tree (range queries) - Persistent Segment Tree - Rope (string with fast operations) ## Input Schema ```json { "type": "object", "properties": { "dataStructure": { "type": "string" }, "operations": { "type": "array" }, "language": { "type": "string", "enum": ["cpp", "python", "java"] }, "includeTests": { "type": "boolean", "default": false } }, "required": ["dataStructure"] } ``` ## Output Schema ```json { "ty

What does the advanced-ds-library skill do?
Provide implementations of advanced data structures
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill advanced-ds-library --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From a5c-ai/babysitter, a repository with 1,642 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
